His liver could be bruised, his heart, and he need steroids and support ready and waiting in case he crashes. There may be occult or frank fractures that he is too shocked to show and his acting normal is just canine stoicism, masking many awful things that can be wrong. He may have lucked out and truly had nothing serious happen but I would have him at the Emergency Vet being x-rayed, neuro/ortho and full checkup while keeping him for observation until all danger periods of time have passed. Please take him in right away.

I agree, he should be checked out by a vet.
